Trilobites (meaning "three lobes") are a group of animals that lived from the Cambrian to the Permian, which was throughout the entire Paleozoic era. A close relative of the modern wood louse, trilobites lived on the sea floor, eating anything they could find. They could curl up into a ball to protect themselves and were one of the first animals to evolve eyes, which allowed them to see food and predators.
